Lens assembly

Abstract

A lens assembly is provided. The lens assembly includes a lens including an optical portion that refracts light and a flange portion that extends from the optical portion; an optical film contacting at contacts a first surface of the lens; and a lens barrel configured to accommodate the lens and the optical film, wherein the optical film may include a straight portion that is formed on a portion of a circumference of the optical film, and the lens may include a linear portion that is formed on the first surface of the lens, and is configured to contact the straight portion of the optical film.

         4 . The lens assembly of  claim 1 , wherein the optical film comprises a polarizing film and a wave plate that are stacked in an optical axis direction. 
     
     
         5 . The lens assembly of  claim 4 , wherein each of the polarizing film and the wave plate comprises the straight portion. 
     
     
         6 . The lens assembly of  claim 4 , wherein the optical film further comprises an anti-reflection film that is stacked on the polarizing film, and
 the anti-reflection film includes the straight portion.   
     
     
         7 . The lens assembly of  claim 1 , wherein a coating layer is formed on at least one of the first surface of the lens and a second surface of the lens. 
     
     
         8 . The lens assembly of  claim 1 , wherein the lens further comprises a decut portion that is formed on an edge of the flange portion of the lens. 
     
     
         9 . A lens assembly, comprising:
 a lens comprising an optical portion that refracts light and a flange portion that extends from the optical portion;   an optical film that contacts a first surface of the lens; and   a lens barrel configured to accommodate the lens and the optical film,   wherein the optical film comprises a first straight portion that extends in a first direction from an arbitrary first outer point of the optical film, and a second straight portion that extends in a second direction from the arbitrary first outer point of the optical film, and   wherein the lens comprises a first linear portion that contacts the first straight portion and a second linear portion that contacts the second straight portion.   
     
     
         10 . The lens assembly of  claim 9 , wherein each of the first linear portion of the lens and the second linear portion of the lens is formed inside an edge of the flange portion of the lens. 
     
     
         11 . The lens assembly of  claim 9 , wherein the first straight portion of the optical film and the second straight portion of the optical film form an obtuse angle with each other. 
     
     
         12 . The lens assembly of  claim 9 , wherein a distance from the first outer point of the optical film to an optical axis in a direction perpendicular to the optical axis is less than a radius of the optical film. 
     
     
         13 . The lens assembly of  claim 9 , wherein the optical film comprises a polarizing film and a wave plate that are stacked in an optical axis direction. 
     
     
         14 . The lens assembly of  claim 13 , wherein each of the polarizing film and the wave plate comprises the first straight portion and the second straight portion. 
     
     
         15 . The lens assembly of  claim 9 , wherein a coating layer is formed on at least one of the first surface of the lens and a second surface of the lens. 
     
     
         16 . The lens assembly of  claim 9 , wherein the lens further comprises a decut portion that is formed on an edge of the flange portion of the lens. 
     
     
         17 . A lens assembly, comprising:
 a lens comprising an optical portion and a flange portion; and   an optical film that contacts a first surface of the lens;   wherein the lens comprises a first linear portion and a second linear portion,   wherein the optical film comprises an anti-reflection film, a polarizing film, and a wave plate,   wherein each of the anti-reflection film, the polarizing film, and the wave plate of the optical film comprises a first straight portion and a second straight portion, and   wherein the first linear portion of the lens is aligned with the first straight portion of the optical film, and the second linear portion of the lens is aligned with the second straight portion of the optical film.   
     
     
         18 . The lens assembly of  claim 17 , wherein a first end of the first straight portion is connected to a first end of the second straight portion at a common point, and
 wherein a second end of the first straight portion and a second end of the second straight portion are connected to each other through an arc surface of the optical film.
